Fly Fishing Grand Lake Stream In Maine
Grand Lake Stream has been regulated as fly fishing
only since 1903. It flows from West Grand Lake into
Big Lake. From there the stream flows into the St.
Croix River. This little short section of river that's only
three  miles long has attracted anglers from around
the World for years. It's big attraction is its native
landlocked salmon and its bigger relative, the Atlantic

There are plenty of places to access Grand Lake
Stream. The eastern side from Big Falls down to the
meadows was donated to the state so it could remain
free of development. You can park and walk in and
fish. There are also easements on the west bank of
the river below Big Lake.

The fishing season opens April 1 through September
30 but there's an extended "catch-and-release"
season from Oct. 1 through Oct. 20. The season for
the salmon really doesn't begin until early May after
the ice leaves the lakes. The salmon follow the smelt,
their favorite food. The salmon also eat the White
Sucker eggs when they spawn. Most of the aquatic
insect hatches begin in late May and continue through
June into the first part of July.

During the middle of the Summer, salmon move into
deep water of either the deeper pools in the river or
the lakes. They return to the river from about the
middle of September through October to spawn.
Generally, fly fishing Grand Lake Stream is very good
during the spawning season.

We should note that Grand Lake Stream also has a
population of brook trout but it isn't generally
considered as good as it is in many other Maine

It should also be noted that there are some very good
aquatic insect hatches and the salmon will take dry
flies from the surface during a hatch. The best hatch is
the Hendrickson hatch which takes place about the
middle of May. There are Quill Gordons, Blue Quills,
Blue-winged olives and other mayflies as well as plenty
of caddisflies during the Summer months.

Strategies, Techniques and Tips:
White Belly Sculpin, Brown Sculpin and our Articulated streamers will work well
year-round. The Black Matuka and olive Matuka Sculpin flies are great flies to use right
Hatches of various species of Blue-winged Olives are possible in the afternoons and
more likely and in greater quantities if the skies are cloudy or overcast.
We recommend fishing a tandem Midge rig under a small strike indicator with the midge
lava as the bottom fly and the midge pupa as the top fly.
Fish the adult midge only when you observe trout feeding on the surface.
Cinnamon Caddis are hatcching. Slate drakes are hating. Little Yellow stoneflies are
hatching. Terrestrials like Carpenter ants, Japanese beetles and hopper are working.
